Abstract:
The evaluation of spatial quality in sound reproduction requires that pertinent
subjective attributes are identified. Furthermore, suitable experimental
designs and statistical methods for dealing with the resulting data are
required. In parallel with subjective experimentation goes the need to identify
physical features of sound fields and signals that relate to spatial
attributes, in order that systems and recording techniques may be designed to
optimize those qualities that relate most strongly to consumer preference. This
demands the development of advanced psycho-acoustic models.
